You have to be renting since pre Dec 2010. Then you just do it on the revenue online site. Need your landlords PPS and address but other than that it’s simple. If you’ve never claimed it and are entitled there’d be 5 years worth coming your way which would be a nice chunk as it used to be worth more going back 200 in 2013, 240 in 2012, 280 in 2011 etc.
All renters are entitled to it as well so yourself & the missus if you have one could claim. It’s also worth more to married people in one of those bizarre tax breaks.
If you are renting accommodation privately (whether in Ireland or outside the State) and pay income tax, you may be eligible for tax relief on part of your rent. You can only claim this relief if you were already renting at 7 December 2010. If you were not renting on that date and you subsequently entered into a rental agreement, you will not be able to claim tax relief on your rent. However, if you were renting at 7 December 2010 you will continue to qualify for this relief even if you enter a different rental agreement after that date. The relief is being phased out and 2017 will be its last year.
*Only the rent for private rented accommodation that you use as your sole or main residence will qualify for tax relief. This includes flats, apartments and houses.*
*You cannot claim tax relief for rent paid to a local authority or a State agency, or for rent paid under a lease agreement for 50 years or more.*
